Let me rephrase the question. Is there any reason anybody would use escrow if the coin is already traded on an exchange?
I assume that using an exchange eliminates the scam risk part, so it does not matter that it is irreversible.  I know an exchange (like Mt Gox) can of course go out of business, but it seems like that risk is less than the risk of the escrow company going out of business.

Right, escrow services on Bitcointalk are more for services and goods being sold.

Thanks, I understand now.

Sent you a PM sir, I really need your help.

Do you escrow bitcointalk accounts?

Wow man. He is fast as lightning and does his work well. Added trust on your profile. Well, now I understand why people escrow higher trust members. Anyways these +9 trust aren't given just for scamming anyone. They are given as a mark of excellence and it is proved.

Still on and open right now.  Currently Acting as escrow for a couple of IPOs as well as some physical goods.

Still offering.

Again.   Anyone who needs to trade should always get an escrow unless they completely trust the other party.

Bump.  I am now online for usually almost 12 hours a day (on and off).

Current acting as escrow for 2 small trades, 2 coding jobs, and 1 signature campaign.

I'll probably be using your service soon..as it appear it's the only one which is actually free...as escrow.ms and others have now started to charge a 1% fee.

Best escrow around I sent a message and then under no time at all the deal was underway and completed within 20 minutes....excellent escrow going  to be using him again.
